I tried this and still can't reproduce it with the standalone testcase.  
  
GNU C version 3.5-tree-ssa 20040301 (merged 20040211) (i686-pc-linux-gnu)  
        compiled by GNU C version 3.5-tree-ssa 20040301 (merged 20040211).  
GGC heuristics: --param ggc-min-expand=30 --param ggc-min-heapsize=4096  
  
Output is the same at -O0, -O1, -O2, and -O3:  
---------------------------------------------------------------  
__alloc_bootmem_core(0xbffff250, 00001000, 00001000, 00000000)  
bm2, found: 0.  
0/1  
reserve 1 bits, starting at 0.  
0/1: 0  
 => (nil).  
---------------------------------------------------------------  
  
The program always exits with code 0.  
  
I'll take a look at the original test case.
